Multiplication and division with decimal point.

Calculation method of decimal point multiplication and division:

Multiplication: ignore the existence of decimal point first. Then use integer multiplication to calculate the product and see how many decimal places a factor has. Starting from the right side of the product, count a few numbers to the left and point to the decimal point.

Division: When calculating division, you can first expand the dividend and divisor to the same multiple, and then operate according to the division algorithm.
